He said the clip reminded him of a news story he read years before about two Russian scientists who had discovered UFOs "bigger than our moon" carrying out a daily, 24-hour operation around the sun, for reasons unknown.

Nevertheless, the new video and the story he read several years previously is enough for Waring to conclude: "They are out there...around our sun, doing god knows what?

"They may actually be controlling the sun, to keep a steady temperature here on earth, or they could be harvesting a very rare and powerful heavy element.

"Let's hope they don't make a mistake and barbecue our planet."

The theory that aliens are conducting clandestine operations around the Earth's life source is popular amongst UFO hunters.

In January, alien-spotter Tyler Glockner, who runs YouTube channel Secure Team 10 , claimed footage taken from NASA's helioviewer showed a UFO 100 times the size of earth "sucking off plasma from the sun".
